A strong cold outbreak has led to the formation of a winter-calibre low in the Tasman (984hPa), backed by a strong, slow moving high in the Bight. We’re seeing the formation of strong S swells from this system, which will peak tomorrow then ease with a following front and deep low well to the south providing a strong S groundswell over the weekend under light winds.

The coming period will be slow swell wise with warmer temperatures ahead of a cold snap next Tuesday/Wednesday.

On Tuesday morning, a cold front will cross the Southern NSW coast, and a new low pressure system will then develop in the central/southern Tasman Sea during the day, strengthening overnight and stalling by Wednesday into a deep Tasman Low, a real beauty. 

Tomorrow will be great across open beaches ahead of a windy south swell Wednesday, best as it eases.
